Terry, my sister just bought a house that is approx. 50 years old and had a fairly new washer in the basement. She says the washer makes a thumping noise and the hoses shake violently when filling. She also reports the washer filling very slowly. I thought that she might have low water pressure, but a plumber apparently checked that and said it was OK. Is there a check valve in a washer that might be failing that could cause this? Just trying to save a visit from the washer repair person.
